hello, i have got a problem with my laptop:

when i have my laptop charging in i get 11,40mb/s of download speed, but when i have it on battery it gets speeds of 268,60mb/s. It sounds really unusual and i dont know what could be causing this problem.

The ping is almost the same, meaning your connection is not down or restricted.
That only points to one culprit - Software using your bandwidth while plugged in.
One piece of software that is restricted from "calling home" while on battery.
Could also be Windows Updates.

Make and model laptop? Hardware specs? OS information?

Verify that only one network adapter either wired or wireless is enabled. As I understand your post you are using wireless so the laptops wired network adapter should be disabled.

= = = =

Using Task Manager and Resource Monitor observe what your laptop is doing.

Use both tools but only one tool at a time.

With the laptop plugged in and the tool window open run your speed test. Observe what system resources are being used, to what extent (%), and what all is using any given resource.

Then do exactly the same process on battery. Make no other changes in between tests.

The objective being to discover and to identify some difference(s) between "plugged in' and "battery".
